Application filed may 12, 1017. Serial No. 142,006. To all whom it may concern: I

. Be it known that we, ALMON V. DEEMER and CLARENCE KELLY, citizens of the United Leiters Ford, in the State of Indiana, have useful Heater for Autohereby declare the folcounty of Fulton, invented a new and lowingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1t appertains to make and use the same.

This invention relates to an improved heater for automobil es, and an object of the invention is to provide a heater to be carried by the exhaust manifold of an automobile engine and having connections with the radiators under the floor of the automobile and provided with connections with the usual automobile radiator, whereby the radiators may be supplied withwater from the radiator of the automobile.

A further object of the invention is to rovide a by-pass pipe on the exhaust mamold through which the exhaust from the engine. may pass, in order to heat 'water in a water specie of said by-pass pipe, which heated water may be-eonveyed to a series of radiators under the floor of the automobile.

A further object of the invention is the provision of into and from the by-pass pipe, which means maybe controlled by the operator of the automoblle.

In practical fields, the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as'liereinafter set drawings, an claimed. Inthe' drawings:.

Figure 1 is a view in side elevation of an automobile, partly broken away, showing the heating system applied thereto in elevation.

Fig. 2 is a sectional view through the radiator under the floor of the automobile.

Fig. 3 is an enlarged view in side elevameans for turning the exhaust comprisi tion of the water heater in the form of a pyl-pass pipe carried by the exhaust mam- Fig. 4 is a view in section of the structure shown-in Fig. 3.

Referring more especially to the drawings, 1 designates the usual exhaust manifold of the engine 2 of the automobile 3, and 4 denotes the conventional form of automobile radiator, which is provided with the usual conduit connections 5 and 6 with the water jacket of said engine. The exhaust manifold 1 is provided with an inclined portion 7, and beyond this portion, said manifold connects to the usual form of mufiier 8. The inclined portion 7 of the exhaust manifold is axially connected to the other portions 9 and 10 of said manifold by means of the fittings 11 and 12. The fittin 12 is connected to the inclined portion 'fliy means of an expansible joint 13. This joint consists of a fitting 14 surrounding the upper forward end of the inclined part 7 and threaded at 15 to the fitting 12, there being a suitable packing 16 between the shoulder 17 and one end of the said fitting 12. It is to be noted thatthe inclined portion or part 7 of the manifold extends partially into the fitting 12. Both fittings 11 and 12 merge integrally into the elbows 18 and 19, the extremities of which are axially. disposed, one toward the other, and are threaded at 20 to the opposite ends of the tube 21. The axially alined extremities of said elbows 18 and 19 have enlargements 22, the adjacent faces of which are provided with annular channels 23 for the reception of the opposite ends of the tube 24, which surrounds the tube 21, and is of sufiicient diameter to provide considerable space between the inner surface of the tube 24 and the exterior surface of the tube 21, for the reception of water from the usual automobile radiator. Arranged under the floor of the automobile are two radiators 26 and 27, each consisting of an undulated conduit 11 the sections 28 arranged in paralle'hsm am? having their oppositev ends com nected in staggered relations by the semicircular fittings 29. A pi e 30 connectstothe enlargement 22 of the e bow 18 and 1s m communication with the water chamber 25 between the walls of the tubes 21 and 24, and which pipe 30 is in turn connected to the radiators 26 and 27, respectively, as shown at 31 and 32, whereby the heated water from the water chamber 25 may be carried to said radiators 26 and 27. A suitable pipe 33 is provided, one end of whlch is connected at 34 to the radiator 26 and its other end is in communication with the water chamber 25, by assin through the enlar ement 22 of the e bow 1 as shown at 35. owever, the 'pipe 33 is in communication with the radiator 27 by means of the short connection 36. -The joints 31, 32, 34 and 36 are provided with suitable paclungs 36, to prevent leakage. It is to be noted that the joint 32 is axiall alined with the joint 34, and the joint, 1 axially alined with the joint 36. By this arrangement, the radiators 26 and 27 may be raised or tilted from horizontal positions to vertical positions, without loosening any of the connections. Said radiators 26 and 27 may be tilted vertically downwardl when not used, or may be turned vertica ly downwardly, rearwardly and then upwardly so as to be directed under the seats of the automobile, and while in such positions, the water from the system will easil and readily pass out when it is desired t at the system be drained. Extending from the automobile radiator, and in communication therewith, and provided with a valve 37, is a pipe 38, which connects to and is in communica tion with the pipe 30, whereby, upon opening the valve 37, water from the radiator i maybe allowed to circulate .into the heating system of the automobile. The pipe 33, just before it connects to the enlargement 22 of the elbow 19 is provided with a pet-cock 39, to remove the air as the heatin system is filled with the water from the ra 'ator 4. A suitable .petacock 40 is provided on the pipe 38 to drain the system. Extending, transversely of where the elbow 19 merges integrally with the fitting 12, is a rod 41, movable with which is afiivotal or hinge flap valve l2. Keyed at on one end of the rod d1, 13 an arm 44 to which a suitable rod 45 is connected, whereb an operator, upon mampulating the re 45, may rock the rod 41, and move the fla valve 42 to the dotted line tion a in ig. 4, in which case, the ex ust from the engine will be by-passed throu fold, there y throroughly heating the water n the chamber 25, and o to the water circulating through the radiators 26 and 27,

pet cock 39, which will allow part 0 steam to pass off, consequently cooling ofi y e tube 21, and then pass out throu h the portion 10 of said maniheat will radiate therefrom and heat the automobile. However, .when the fla valve is closed, as shown in full lines in ig. 4, the greater portion of the exhaust will take its usual course throu h the inclined portion 7 of said manifol It is to be noted that the heater carried upon the manifold may be disposed vertically or upon an inclination, in order that the inlet of the exhaust into the tube 21 will be higher than the outlet from the tube 21.

It is to be noted that the heating system for the automobile may be filled with water from the automobile radiator 4, and when said system is filled, the valve 37 may be closed, and in this case the heating system may operate independent of the circulating water system of the radiator 4 and the engine, and viceversa. Furthermore, when it is desired to drain the heating system, the valve 37 may remain closed, and the valve cock 40 open, it being at the lowest point of the system, in which case the entire system may be drained. The circulation of the steam to the radiators 26 and 27 may be regulated by opening tfie the system.

The invention havin been set forth, what I is claimed as new an useful, is:-

1. In a heat exchange device for automobile heaters, a air of elbows spaced apart, each havin a end connected to the exhaust mani old of the, automobile, the other end of each elbow being internall threaded and having a flan provided wit an annular recess, an inclined heater comprisin an inner tube engaging the interior threa s of the elbows, thereby providin a by-pass passage, the o posite ends 0 which are in communication with the exhaust manifold through said elbows, and an outer tube entirely surroundi and spaced from the: in
